(Cl. 5Fl-l) ABSTRACT F THE DlSClLSURE A spinning machine having an elongated frame cornposcd of a plurality of longitudinally extending identical frame sections, each having a -pair of identical transverse members connected to each other and each transverse member having a plane end face abutting against a corresponding plane end face of the transverse member of a section adjacent thereto, and combined connecting and aligning means connecting abutting transverse members of adjacent sections to each other in fixed aligned relationship in such a manner so that upon removal of the combined connecting and aligning means, the frame sections may be moved relative to each other in direction of said plane end faces without shifting the same in direction transverse thereto.

The present invention relates to textile machines and more particularly to a textile machine for ringless continuous spinning which is divided in a plurality of longitudinally extending identical sections permitting an easy assembly, disassembly, as well as transporting of the machine.

Various constructions of spinninv machines are known which include a great number of working elements, such as spindles, iyers, and bobbins closely spaced from each other in longitudinal direction of the machine which consequently results in a machine of great length. Such machines well known in the art have a common drawback, that is that they must be first assembled in the manufacturing plant, where the machine is to `be tested under its own drive, whereafter the various machine components, after being lproperly numbered, are disassembled and lpacked into appropriate shipping cases in which they are sent to the user, where the components are unpacked and reassembled again in proper order. These operations require vast assembly rooms and involve also considerable expenses, as Well as a great number of qualiiied workers.

lMachines of this type are also known which comprise an elongated frame structure composed of various sections which are rigidly interconnected at the iinal assem- -bly by welding or the like in which the various sections are however not identical and therefore not interchangeable with respect to each other. The rigid interconnection of the frame sections by welding is not only complicated, but such a construction disregards also the problems of noise and vibration. ln fact in such a construction the rigidly connected metal sheet frame parts act as resonators.

Furthermore, in sectionalized frame structures of machines of this type known in the art no provisions have been made for securing and properly axially aligning a plurality of high speed shafts on the machine frame in such a manner that the shafts can be easily assembled and disassembled with the plurality of frame sections.

It is an object of the present invention to overcome the disadvantage of textile machines of the aforementioned kind.

It is an additional object of the present invention to provide for a sectionalized textile machine of the aforementioned kind Which can be easily assembled and disassembled and in which the various sections of the machine can be interexchanged as desired.

With these objects in view, the textile machine according to the present invention, particularly a spinning machine, mainly comprises elongated frame means divided in a plurality of longitudinal identical frame sections in which each section has at opposite ends thereof identical transverse members and in which one of the transverse members of each section abuts against a corresponding transverse member of the section adjacent thereto. The transverse members of each section being connected by connecting means and the arrangement com- Iprises further combined aligning and connecting means connecting abutting transverse members of adjacent sec` tions of each other in properly aligned relationship.

Preferably, each of the transverse members at opposite ends of each section is provided at opposite side faces thereof which extend in longitudinal direction of the frame means with recesses extending from the respective side face into the transverse member and supporting means are provided in the recesses for supporting elongated drive shaft means therein which extend in longitudinal direction of the frame means. Each of the drive shaft means includes preferably a plurality of shaft sections having a length substantially equal to the length of the frame section and including coupling means for releasably coupling the shaft sections of each shaft means to each other, which coupling means are: at least in part located in the aforementioned recesses.

The connecting means for connecting the transverse members of each section with each other may include an elongated tube extending in longitudinal direction of the frame means and connecting lower portions of transverse members of each section to each other as well as a plurality of longitudinally extending horizontal and vertical plates extending fixed to upper portions of the transverse members of each section and arranged to form at least one, or preferably two, adjacent air ducts. The elongated tubes of adjacent sections are aligned and communicate with each other and so are the air ducts formed by the horizontal and vertical plates of each section.

Preferably, sealing means of elastomeric material are provided between end edges of the plates forming the air ducts of adjacent sections, to provide for a perfect seal of the air ducts of adjacent sections, and to also prevent the air ducts from forming sound resonators.

The combined aligninff and connecting means between adjacent and abutting transverse members of adjacent sections are preferably constituted by screws and dowel pins extending through appropriate bores of abutting transverse members. i

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its constitue-tion and its method of operation, together with additional objects and advantages thereof, will be best understood from the folios/ving description of specific embodiments when read in connection with the accompanying dra-wings, in which:

Referring now to the drawings, and more specifically to FIG. 1 of the same, it will be seen that the machine of the presen-t invention includes a machine frame formed of a plurality of identical sections 1. The frame shown in FIG. 1 comprises two o-f such sections, but it is understood that a machine according to the present invention may also include a plurality of frame sections more than two. The sections 1 forming the machine frame are substantially identical and each section includes a pair of identical transverse members 4 in the form of an integral frame structure, as best shown in the perspective view of FIG. 3 and respectively arranged at opposite ends of each section. The transverse members 4` may for instance be for-med from cast iron. The transverse members 4 are identical and symmetrically arranged with regard to a vertical plane of symmetry. Each of the transverse members 4 includes (FIG. 3) a pair of substantially upright portions 41 coni nected at the upper end thereof by transverse portion 42, intermediate its ends by transverse portion 43 and at a lower portion thereof by a transverse portion 44. The transverse portion 44 is provided with a central opening 5a therethrough about which a plurality of tapped bores 5b are arranged for a purpose as will be described later on. Each of the upright portions 4a is provided at an outer face thereof with `a plurality of substantially semicylindrical recesses 25 `for a purpose `as will be described later on and on the inner faces thereof the upright portions 41 are provided between the transverse portions 42 and 43 with the plurality vof inwardly projecting bosses or projections 4b which are provided with tapped bores. Likewise, the transverse portion 43 is provided at opposite outer ends thereof with bosses having upper substantially horizontally extending faces 4c from which tapped bores extend into the frame member.

Connecting means connect transverse members 4 of each frame section 1 to each other. The connecting means preferably comprise an elongated tube 5 aligned with the openings 5a in the lower part of each transverse member 4, and having at opposite ends thereof flanges connected by lscrews or the like to the tapped bores 5b arranged about each opening 5a. The connecting means further comprise a pair of vertical plates 5 (FIG. 2) fixed by screws or the like to the bosses 4b of each transverse member 4 and three horizontal plates 9, 10 and 19 connected to the vertical plates 6 and arranged with respect thereto, as best shown in FIG. 2 to form a pair of air channels 7 and 20. The connecting means may further include an additional pair of vertical plates 8, of a width smaller than the plates 6 and fixed to outer faces of upright portions 41 of each transverse member of one section. The lowest of the horizontal plates, that is the plate 9 preferably extends beyond the verticail .plates 6 and serves to carry a plurality of guide pulleys 11 and 12, the shafts of which are mounted in a known manner in rubber blocks or ythe like. Likewise, the vertical plates 6 serve to respectively mount thereon a row of lower guide pulleys 15 and .16 and a row of upper guide pulley 15 and 4 16 as best shown in FIG. 2. The shafts of these pulleys are likewise mounted in a known manner in rubber blocks fixed to the plates 6. The vertical plates 8 serve to support thereon a plurality of spinning apparatuses, not shown in the dratwiug.

The machine includes further a plurality of shaft means each comprising shaft sections 24 having a length substantially equal to the length of each frame section 1 and being coupled to each other at adjacent ends by coupling means as best shown in FIGS. 5 and 6. For this purpose the opposite ends of each shaft section 24 are provided with coupling members 27 and 28 which are respectively turnalbly supported in bearings 29 and 32 located in part in the recesses 25 formed in each transverse member 4. The coupling member 27 at one end of one shaft section 24 is iixedly connected thereto and provided with `outer peripheral teeth 3G adapted to engage with inne-r peripheral teeth 31 on the coupling member 28 of the shaft section adjacent there-to. The coupling member 28 is fixed by a sliding key Z6 to the end of a shaft section 24 for rotation with the latter and movable in axial direction together with the bearing 32 between an engaged position as .shown in FIG. 5 in which the teeth 3() and 31 are interengaged with each other, and a disengaged position as shown in FIG. 6 in which the aforementioned teeth are disengaged from each other. In both positions the coupling member 28 may be fixed to the end of the shaft section 24 by a set screw 33 or the like. Half of the bearings 29 and 32 are loc-ated in the recesses 2S and clamping members 34 in the form of half-cylindrical shells xed to the outer faces of the upright portions `41 of each transverse member 4 extend .over the outer half of each bearing to hold the latter properly in place in the respective recess.

The transverse members 4 at facing ends of adjacent trarne sections 1 abut against each other, as best shown in FIG. 1 and the abutting transverse members 4 are connected to each other in properly aligned relationship by screws 37 and dowel pins 35 as best shown in FIG. 4, which respectively extend through appropriate bores in abutting transverse members 4. The dowel pins 35 may be provided with a central threaded bore therethrough for facilitating removal of the respective dowel pin from the bore in the transverse member in which it is tightly fitted.

The spinning machine includes further a pair of casings 2 and 3, as best shown in FIG. 1, which are respectively arranged at the ends of the frame sections 1 facing away from each other and each of the casings 2 and 3 has an end wall against which the transverse member 4 at the aforementioned end of the respective frame section abuts, connected thereto by screws `and dowel pins in the same manner as the transverse members 4 which abut against each other are connected to each other. A belt 117 is arranged in an endless loop about the pulleys 15 and 15 and a corresponding belt 18 is arranged about the pulleys 16 and 16. The belts 17 and 18 extend through appropriate openings in the end walls of the casings 2 and 3 and over guide pulleys located in these casings as indicated in dotted lines in FIG. 1. The guide pulleys located in the casing 2 are driven by means of belt drives from the motors M1 and M2 as indicated in FIG. 1. Belts 13 and 14 extend respectively in a loop about the row of guide pulleys 11 and 12, as shown in FIG. 2 and the belts 13 and 14 likewise extend through openings in the end Walls of the casings 2 and 3 to be guided therein about appropriate pulleys and the pulleys for instance located in the casing 3 for the belts 13 and 14- are respectively driven by motors M3 and M4 located one behind the other and only one of which is illustrated in dotted lines in FIG. l. `Coupling means as shown in FIGS. 5 and 6 are provided at the ends of the shaft sections 24 in the transverse member 4 abutting against the end wall of the easing 3 and in this end Wall of the casing to releasably connect the shaft sections to a plurality of short drive shafts, not shown in the drawings, located in the casing 3 and driven by a motor or motors likewise not shown in the drawing, in a known manner. The drive motors in the casing 2 as well as the drive motors in the casing 3 may -be interconnected vwith each other for instance for simultaneous starting and stopping by wires which preferably extend through the tubes 5 from one casing to the other. The belts f3, I4, 17 and 18 serve to drive in a known manner individual spinning heads of the spinning machine, which are for claritys sake not illustrated in the drawings, and the shafts 24 serve to drive other movable elements of the spinning machine, likewise not shown in the drawings.

If the frame sections ll of the spinning machine are relatively long, it is preferred to arrange between the transverse members i at the end of each Section 1 and equally spaced from both transverse members an additional transverse member 38 which may be constructed in a similar manner as the transverse member d shown in FIG. 3. In this case additional bearings may be provided for the shaft section 2li located in part in recesses formed in the side faces of the transverse members 3S and properly held therein by clamping members 34 as shown in FIG. 7. In this case the vertical plates 6 and 8 as well as the horizontal plates 9, It) and 19 may be formed from shorter sections which are connected to the transverse members 38 as shown for the plates 8 in FIG` 7.

Appropriate sealing means dl are provided between abuttting end edges of the aforementioned plates which form the air ducts 7 and Ztl, as shown in FIG. 8 for the abutting edges of the plates d. As seen in this gure, each of the plates n is provided at the end edge thereof facing the end edge of the next plate with a substantially semicylindrical groove and an elongated sealing strip 41 of rubber or another elastomeric material of circular cross section is located in the grooves of the facing end edges of the plates 6 to provide a proper seal between the latter. It is understood that similar sealing means are provided between facing end edges of all of the aforementioned plates to provide not only a perfect airtight seal, but to reduce also transmission of noise from one section to another.

The air ducts '7 and Ztl are continued in downward direction through the casings 2 and 3 as schematically indicated in FIG. l by dotted lines to communicate at the bottom ends thereof with channels 7a and 20a which are respectively connected to blower and suction means to create an underpressure in the air duct 7 and an overpressure in the air duct 20. As schematically indicated in FIG. 2, a plurality of suction nozzles 23 communicate with the interior of the air duct 7 and which extend with outer ends through appropriate openings in the plates 8 so that dust, lint or other foreign matter present at the outside of the spinning machine is continuously sucked through the nozzle 23 into the air duct '7 and from their to appropriate filter means not shown in the drawing so that accumulation of dust and lint on the machine is prevented. Tubes 2l communicate with the interior of the air duct and these tubes are connected at the outer ends thereof to devices of the spinning machine in which compressed air is needed.

Adjusting screws 39 project downwardly from the bottom walls of the casings 2 and 3 and from the lower transverse portions of the transverse members 4 and 38, engaging with the bottom ends thereof small plates 40 resting on the floor on which the spinning machine is mounted. The adjusting screws 39 are adjustable in a known manner so that the elevation of the casings 2 and 3 and that of the transverse members 4 and 38 may be adjusted to a limited extent.

The machine above-described may be assembled in the following manner:

For instance, the casing 2 may be first placed on the floor and appropriately adjusted by means of the screws 39. Then the left frame section 1, as viewed in FIG. 1, is pushed against the right end wall of the casing until the left transverse member it of this section abuts against the end Wall of the casing Z. The height of this section 1 is then adjusted by means of the adjusting screws 39 and subsequently thereto the left transverse member d, as viewed in FIG. l, is connected to the right end wall of the casing by screws 37 and dowel pins 35 in the manner .as described above. Subsequently thereto the right frame section l, as viewed in FIG. l, is placed on the floor and the height thereof is properly adjusted by the adjusting screws 39' and the abutting transverse members l of the two sections are connected to each other by screws 37 and dowel pins 35i. Finally, the casing 3 is placed on the floor with the left end wall thereof, as viewed in FIG. l, abutting against the right transverse member of the second frame section, the elevation of the casing 3 is properly adjusted by means of the adjusting screws 39 and then the end wall of the casing 3 is connected to the transverse member l abutting thereagainst by screws 37 and dowel pins 3S. The clamping members 3d are then removed from the transverse members 4 and 38 and the bearings Z9 and 32 about the coupling members at the end of the shaft sections are placed in the recesses 25 of the transverse members d and 38, after which the clamping members 3dr are connected to the respective transverse members to hold the aforementioned bearings properly in place. Subsequently thereto, the movable coupling members 23- on the end of the shaft sections 2d are engaged with the corresponding coupling members 27 at the ends of the shaft sections adjacent thereto .and the movable coupling members are held in engaged position by the set screws 33, The clamps 3d are then properly tightened to hold the bearings 29 and 32 against rotation. Finally, the aforementioned driving belts are slipped over the pulleys.

The machine thus assembled provides for the necessary rigidity and it possesses also very good antivibration properties so that the over-all noise of the machine is reduced.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of spinning machines or the like differing from the types described above.

While the invention has been illustrated and described as embodied in a spinning machine having a frame cornposed of a plurality of equal frame sections, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
